The chip 14nm means that in the process of producing the CPU, the precision of the integrated circuit is 14. The higher the density of the IC circuit design, means that in the same size area of the IC, you can have a higher density, more complex function of the circuit design. Process 14nm refers to the CPU transistor gate circuit of 14nm. Or the size of the transistor gate circuit, expressed in nanometers (nm). Thumbs up for technology!
The chip with 14 nm process means that the distance between the circuit inside the chip and the circuit is 14 nm; Nanomanufacturing process refers to the process of manufacturing a CPU or GPU, or refers to the size of a transistor gate circuit, in nanometers (nm)
